  • Patent number: 5081360
    Abstract: An irradiating apparatus comprises a bucket group consisting a plurality of buckets spaced equally from each other and connected to a first endless chain, and a roller group consisting of a plurality of roller located under the bucket group. Each bucket comprises a barrel shaped body having a bottom which has a plurality of openings. Moreover, the bucket receives an article to be transferred such as preform and transfers it in a horizontal position therein. The rollers are connected to second endless chains. A pair of rollers are arranged parallel to each other in the transfer direction. The roller has a plurality of lands which intrude in the openings of the bucket. A pair of rollers are rotated in the same direction to rotate the article to be transferred. The roller group travels at the same speed in the same direction as those of the bucket.

  • Patent number: 5056649
    Abstract: An inverting mechanism according to the present invention comprises an inverting body for inverting which includes a plate member fixed to each of a plurality of carriers connected to an endless chain and four inverting elements rotatably supported on each plate member at circumferential positions spaced equidistant from each other, and an inverting cam provided on a rack rail on which the inverting elements roll. The inverting element on the body traveling on the rail drops into a groove formed in the inverting cam to rotate the body about the dropped inverting element as another inverting element rolls along a projection on the reversing cam to downwardly direct the top opening of the carrier and thereby an article to be transferred can be taken out of the carrier.
